AIMS: The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM...

Pulmonary artery reconstruction in lung cancer surgery is an effective surgical method to avoid pneumonectomy that leads to longer survival times with few adverse effects. The pericardium is often used for the interposition of a prosthetic conduit. A pericardial conduit can be easily and precisely constructed by surgical stapling, which facilitates pulmonary artery reconstruction. In this report, the process and pitfalls of surgical stapling are described.

A 6-year-old girl with unbalanced atrioventricular septal defect, hypoplastic right ventricle, and severe common atrioventricular valve regurgitation developed patient-prosthetic mismatch. At 6 months old, she underwent primary one and one-half ventricle repair and replacement of left side atrioventricular valve. A catheter examination showed that her right ventricular end-diastolic volume increased from 39.4 mL/m(2) 1 year after to 70 mL/m(2) 3.5 years after the previous surgery. Thus, at the timing of redo left side atrioventricular valve replacement, she was converted successfully to biventricular circulation...

BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

BACKGROUND: The cross-sectional morphology of the prosthetic knee is crucial to understanding patellar motion and quadriceps strength after total knee arthroplasty. However, few comparative evaluations of the cross-sectional morphology of the femoral trochlea have been performed in the native knee and currently available femoral implants, and the relationship between the trochlear anatomy of prosthetic components and post-operative patellofemoral complications remains unclear. We aimed to investigate the differences in cross-sectional morphology of the femoral trochlea between native knees and prosthetic femoral components...

The neural command from motor neurons to muscles - sometimes referred to as the neural drive to muscle - can be identified by decomposition of electromyographic (EMG) signals. This approach can be used for inferring the voluntary commands in neural interfaces in patients with limb amputations. This paper proposes for the first time an innovative method for fully automatic and real-time intramuscular EMG (iEMG) decomposition. The method is based on online single-pass density-based clustering and adaptive classification of bivariate features, using the concept of potential measure...

A major issue in bone tissue engineering is the selection of biocompatible materials for implants, to reduce unwanted inflammatory reactions and promote cell adhesion. Bone tissues growth on suitable biomedical implants can shorten recovery and hospitalization after surgery. Therefore, a method to improve tissue-implant integration and healing would be of scientific and clinical interest. In this work, we permeated Polydimethylsiloxane (PDMS) into Carbon/carbon (C/C) composites (PDMS-C/C) and then coated it with 4, 5-dihydroxyanthraquinone-2-carboxylic acid (Rhein) to create Rhein-PDMS-C/C to increase its biocompatibility and reduce the occurrence of inflammatory reactions...

Dynamic load exists in numerous biomechanical systems and its identification signifies a critical issue for characterizing dynamic behaviors and studying biomechanical consequence of the systems. This study aims to identify dynamic load in the dental prosthetic structures, namely three-unit implant-supported fixed partial denture (I-FPD) and teeth-supported fixed partial denture (T-FPD). The three-dimensional (3D) finite element (FE) models were constructed through patient's computerized tomography (CT) images...

The functional capabilities of individuals with upper limb disabilities are assessed throughout rehabilitation and treatment regimens using functional outcome measures. For the upper limb amputee population, there are none which quantitatively take into account the quality of movement while an individual is performing tasks. In this work, we demonstrate the use of an integrated movement analysis framework, based on motion capture and ground reaction force data, to capture quantitative information about how subjects complete a commonly used functional outcome measure, the Box and Blocks Test (BBT)...

Accelerometers can be used to augment the control of powered prosthetic arms. They can detect the orientation of the joint and limb and the controller can correct for the amount of torque required to move the limb. They can also be used to create a platform, with a fixed orientation relative to gravity for the object held in the hand. This paper describes three applications for this technology, in a powered wrist and powered arm. By adding sensors to the arm making these data available to the controller, the input from the user can be made simpler...

Surgical therapy of cardiovascular diseases frequently requires replacement of diseased tissues with prosthetic devices or grafts. Calcification is the main reason for the degeneration of implanted grafts. However, some factors reduce stenosis and attenuate calcification of implanted grafts. In this study, we used an autologous induced adipocyte cell-sheet (IACS) as a drug delivery system to determine whether its secretion ability has a beneficial effect on the remodeling process of grafts in a rat subcutaneous model...

Hemin, the oxidized prosthetic moiety of hemoglobin, has been implicated in the pathogenesis of acute chest syndrome (ACS) in sickle cell patients by virtue of its endothelial-activating properties. In this study, we examined whether hemin can cause lung microvascular endothelial barrier dysfunction. By assessing transendothelial resistance using electrical cell impedance sensing, and by directly measuring trans-monolayer FITC-dextran flux, we found that hemin does cause endothelial barrier dysfunction in a concentration-dependent manner...
